Charles Ellicott Commentary Leviticus 26:44

"And yet for all that, when they are in the land of their enemies, I will not reject them, neither will I abhor them, to destroy them utterly, and to break my covenant with them; for I am Jehovah their God;" — Leviticus 26:44 (ASV)

And yet for all that. —Better, And yet even so; that is, even if they remain exiles in foreign lands for a long time, this is no proof that God has finally cast them off, has given them over to destruction, and abrogated His covenant with them. He is always their God and will keep His covenant forever.
